SAMPLEB.

a lication filed August-25, 1920. Serial No. 4os,oae'

To all whom it may concern:

Be it knownthat I, JOHN VANDEMOER, a citizen of the United States, residing at El Paso, in the county of El 'Paso and State of Texas, have invented certain new and useful Improvements in Samplers, of which the following is a specification.

This invention relates to samplers which are capable of deflecting or cutting out from athoroughly and uniformly mixed body of fluids, ore, grain or other granular or disintegrated material a determined'percentage of'the material passing through the ,ap-.

paratus.

{The objects of the invention are First, to construct a sampler of the character described which will thoroughly mix the material passing through the same and at the Sametime cut out a sample which has been so mixed in a quiet and most efficient manner.

Second, to provide a combined mixer and sampler which can be easily installed, re-

quires small space and head room, a minimum power to operate and at the same time readily permit .the percentage of the material to be cut out as a. sample to be varied in the shortest interval of time without in acteristics and relative arrangements of'elements which will be hereinafter more fully.

disclosed and particularly pointed out in the appended claims.

In the two sheets of drawings in which similar reference characters indicate the same parts in the several figures,

, Figure 1, is a longitudinal section of the improved sampler.

Figure 2, is a section on line of Fig.

1 when cutting a one-fourth sample.

Figure 3, is a section on line 22 of Fig. 1 when cutting a one-eighteenth sample.

Figure 4, is a section on line 44 of Fig. 1.

of the opening K. One of flanges is preferably provided with a scale Figure 5, is an enlarged and fragmentary view of the cutting opening of the sampler. Figure 6, is a sectional view' on line 66 of Fig. 5.

Figure 7 is a longitudinal section of a modified form or duplicate sampler.

Figure8, is a section on line 88 of Figure 7, and

Figure 9 is a section on line 9-9 of Fig-. ure' 7.

Referring to Figures 1 to 6 of the drawings, Sis a revolving imperforate cylinder supported by the spiders H carried by the rotating shaft I rotatably supported in bearings P, resting on supports 0, said shaft and cylinder are slightly inclined=and are rotated by any suitable pulley Q, as shown and will be readily understood.

E is, a chute 'which receives the material to be sampled and as shown feeds said ma-- terial into the upper and elevated end F of the cylinder S. G, G are ribs or other suitable-obstructions or lifting devices secured on the innerside of the cylinder which are adapted to repeatedly pick up the material passing through the sampler and thoroughly and uniformly mix the same before certain determined proportions are cut out form ing the samples to be presently described.

K is a opening near the lower end M of the revo ving cylinder and is provided with i an adjustable gate R which can be moved or slid between suitable guiding flanges R, R, see Figs. 1, 5 and 6, by means of handle X, in sucha manner as to re ulate the size Z-to indicate degrees, as shown in Figure 5. Said gate B may be locked or held in its adjusted position by means of clamp screws Y as will be readily understood. is a circular imperforate plate centrally arranged and attached to a spider H, of the.

revolving cylinder Sv near the opening K for the purpose of preventing the material being thrown into the sample opening orhole K and impair the proper and accurate working of the sampler. F I

L is a chute for receiving the material as it is cut out by the sampler when the opening K, of the cylinder S passes over it, while N is a second chute arranged at the lower end of the cylinder S, to receive the major and remaining material passing from the1 s7ampler, as clearly shown in Figs. 1 an I o the guiding T indicates a stationary outer casing or housing enclosing the sampler, which may be provided with any suitable closing means provided with a look so as to prevent accessibility to the sampler or tampering with its senor adjusted gates or openings.

The modification of the invention shown in Fi res 7 8 and 9 is substantially the same in its essential parts as that shown in Figures'l to 6 inclusive, except in having one opening or sample cut out K, asshown in saidFigures 1 to 6, there are two holes,

. cated by the arrow by power being applied to the pulley Q, the material which drops through the chute into the upper end of the cylinder is taken up or elevated by the ribs G or other similar means and permitted todrop down, which action upon the material 1s reggeated and continuous. This repeated tum ward path or sliding through the cylinder 7 is such that when the materialhas reached thezone in the interior 'of the cylinder S where the opening or cut out hole K i located, the material is thoroughly an uniformly mixed or intermingled and a certain proportion or percentage of the material passing through the cylinder S or sarn pler will quietl automatically and intermittently pass t rough saidopening or cutout hole K into the chute- L to be collected in a sam le hon er, not shown, The remalnder of thematerlal Wlll continue in its downward and 1 sliding movement tothe lower end M- of the cylinder and pass by way of the chute N to any suitable storage hopper or chamber, not shown. The baflie or circular plate J revents an material liftedby the ribs G rom being t rown into the cut-out or sampling opening K before the same-"reaches the sampling zone of the cylinder S;

If 't is desired to va the ratio or per-, centage of the sample 0 the total material passing through theapparatus all that is necessary is to vary the cross-sectional area of the,opening K'which' can be easily and quickly efi'ectedby sliding'the gate R in its guiding flanges R R, thereby varying in de rees along the circumference of the cylin er, the width W of the opening -.K,

. and as shown in Figure 5, the "width is twenty degrees and the cut or sample will be twenty three-hundred and sixtieths or one-eighteenth, if one cutting or sample hole positions of the cut out of larger diameter it so.

ling of the material in its down- K is provided, and'one-ninth if two holes are employed. After the gate R is properly adjusted, the clamp screws V, V, are screwed down to bind said gate to the cylindcn, The

dimensionV or longitudinal length ofthe holeK is varied, depending on the size of thematerial passin through'the sampler, and as will be readily seen an ratio, part or sample of the material, in ependent of the material operated upon canbe secured and if materials are to be operated upon which do not readily and uniformly. commingleor mix, the cylinder S is made longer and the number of ribs G are multiplied, orif desired the inclination of the cylinder .8 may be varied to retard or accelerate the movement of the material through the apparatus, and it has also been found in. the

practical operation of the invention that the distance W of the opening K should never be smaller than the distance U.

It will be apparent that as soon as the cut-out hole traverses the stream of the ,material passing throi'igh the sampler it will drop into the chute L and that said stream is. cut normal to the direction of the stream which assures a proper operatlon for securing a correct gample.

In Figure 2, the cut-out opening is fortyfive degrees and the cut will be "one-eighth and when the openin is ten degrees, as

a'shown in Figure 3," t e cut will'be onethirty sixth part of the material handled when one opening is used, and while I have shown and described one or two openings this number could be varied withoutin any way de arting from the s irit of the invention' and will depend on t v e size and nature of the material being sampled.

From the foregoing disclosure of the construction and operation of the device all the. I

objects and advantages briefly outlined in the statement of invention are frilly and e ferred'form of my apparatus has been disclosed, it is clear that many modifications -will readily su gest themselves without departing from t e essential elements of the invention and clearly be within the scope of the claims. Y j

What I claim is 1. -A-sampler comprising ahollow rotary iently carried out, and while the preinclined cylinder, means for feeding material within the cylinder at its upper end, means wlthin the cylinder and at its up er section for mixing the material ted w1t in ings in the lower section of and rotating with said cylinder to divert .to the outside of said cylinder a certain proportion of the mixedmaterial passing through said cylin der, and means within the cylinder preventin the. material. while being. mixed from being thrown into said cut out openings.

2. A'sampler comprising a hollow rotary 'the cylinder, a plurality of cut-out openinclined cylinder, means for feeding mate rial within the cylinder at its upper 'end, ribs within the cylinder and at its up r section for mixing the material fed vW1 the cylinder, a cut-out opening in and rotating with said cylinder at the lower section and removed from that in which the material is fed and mixed to divert to the outside of said' cylinder a certain proportion of. the mixed material passing through said 10 I cylinder, an adjustable gate to vary the size of said cut-out opening, and a baflle within said cylinder to prevent the material while beingmixed being thrown into sail cut-out 0 g.

In testimony whereof I aflix my signa-' ture. JOHN VANDEMOEB.
